Tesla patent teases Automated Turn Signaling system using cameras, radar and sensors
Tesla is preparing to roll out the first Full Self-Driving features of its fleet with the upcoming release of Software Version 9. While Tesla has not revealed the features that would comprise the first capabilities of its FSD suite, an automated turn signaling system appears to have been teased in a patent filing, which was published today.
The patent filing is simply dubbed as “Vehicle Technologies for Automated Turn Signaling,” and it describes a system that utilizes the electric cars’ suite of cameras, radar, and ultrasonic sensors to enable the vehicle to activate its turn signals without human input. The patent’s international filing date was listed on February 22, 2018, and its inventor was listed as Sean Haight, Ph.D., a Staff Passive Safety Test Engineer at Tesla.
Tesla notes in its patent filing that turn signals today, including those that are equipped with smart features, still rely on human input to be activated. Since manual activation of the turn signals is still required, it is not rare for the safety feature to be enabled too late when drivers navigate into a turn. The electric car maker notes that this creates a dangerous situation, particularly in areas where vehicles are traveling at high speeds.
The patent filing outlines a system that uses a processor that would analyze input from the electric cars’ suite of sensors to determine if the vehicle is turning left or right. By analyzing a series of factors such the movements of the steering wheel, the vehicle would be able to activate its turn signals automatically. Following is a diagram outlining how Tesla’s Automated Turn Signaling system would work.
Tesla describes the system in the following excerpt from the patent filing.
“An embodiment includes a method of automated turn signaling, the method comprising: determining, via the processor, that a vehicle will cross a lane line or turn based on a measured steering angle value that is within a value range stored in a memory, wherein the car includes the processor, the memory, and the turn signal source; and activating, via the processor, the turn signal source based on the determination that a vehicle will cross a lane line or turn.
“An embodiment includes a storage device having stored therein a set of processor executable instructions which, when executed by an electronic processing system, cause the electronic processing system to: determine a path of travel of a first vehicle relative to a lane line based on a first set of data received from an image capture device of the first vehicle; determine that a second vehicle is present within a predetermined distance from the first vehicle based on a second set of data received from a reflective wave detector; activate a turn signal source of the first vehicle when (a) the first vehicle has a travel path and a steering angle such that the first vehicle will cross the lane line or effect a turn, and (b) the second vehicle is present within the predetermined distance from the first vehicle.”

Automated Turn Signaling is a feature that would be incredibly useful for drivers, particularly those who travel through high-speed highways on a consistent basis. The automatic feature outlined in the patent filing is also a perfect fit for Tesla’s Autopilot and its upcoming Full Self-Driving suite. Autopilot, after all, has already reached a certain level of refinement on freeways, but the driver-assist system still leaves much to be desired when attempting to perform actions such as highway on-ramp to off-ramp maneuvers. This capability was specifically mentioned by Stuart Bowers, a member of Tesla’s Autopilot team, back in the company’s Q2 2018 earnings call.
“A lot of the focus is on Autopilot V9, which is our sort of on-ramp to off-ramp solution that’s going to automatically attempt to change lanes, understand what lane the car is in, understand the route the user wants to travel and take that route for the user and ultimately hand back control to that user which is kind of stay in control,” Bowers said.
Automated Turn Signaling also appears to be a perfect fit for a feature teased by Elon Musk himself in the most recent earnings call. While speaking about Tesla’s upcoming Full Self-Driving suite and the upcoming improvements to Autopilot, Musk teased a feature called Integrated Navigation, which would allow vehicles to navigate towards a set destination.
“Integrated navigation. So, you’d like by the way, a little tip for if you’re driving Model S or X or 3, is if you just tap the Navigate button and just drag down, it will automatically navigate you to your home or work, depending upon where you are. That’s a pretty cool feature,” Musk said.
Tesla’s Software Version 9 is expected to see a wide rollout sometime in September. Apart from improved Autopilot capabilities and the introduction of the first Full Self-Driving features, Tesla is also introducing some fun, new Easter Eggs for V9’s release. Among these are some classic Atari titles such as Pole Position, which would have its controls linked to the electric cars’ steering wheel.
It appears that Tesla may be preparing to roll out some subscription-based services soon. Based on the observations of a Wales-based Model 3 owner who performed some reverse-engineering on the Tesla mobile app, it seems that the electric car maker has added a new “Subscribe” option beside the “Buy” option within the “Upgrades” tab, at least behind the scenes.
A screenshot of the new option was posted in the r/TeslaMotors subreddit, and while the Tesla owner in question, u/Callump01, admitted that the screenshot looks like something that could be easily fabricated, he did submit proof of his reverse-engineering to the community’s moderators. The moderators of the r/TeslaMotors subreddit confirmed the legitimacy of the Model 3 owner’s work, further suggesting that subscription options may indeed be coming to Tesla owners soon.

Tesla’s Full Self-Driving suite has been heavily speculated to be offered as a subscription option, similar to the company’s Premium Connectivity feature. And back in April, noted Tesla hacker @greentheonly stated that the company’s vehicles already had the source codes for a pay-as-you-go subscription model. The Tesla hacker suggested then that Tesla would likely release such a feature by the end of the year — something that Elon Musk also suggested in the first-quarter earnings call. “I think we will offer Full Self-Driving as a subscription service, but it will be probably towards the end of this year,” Musk stated.
While the signs for an upcoming FSD subscription option seem to be getting more and more prominent as the year approaches its final quarter, the details for such a feature are still quite slim. Pricing for FSD subscriptions, for example, have not been teased by Elon Musk yet, though he has stated on Twitter that purchasing the suite upfront would be more worth it in the long term. References to the feature in the vehicles’ source code, and now in the Tesla mobile app, also listed no references to pricing.
The idea of FSD subscriptions could prove quite popular among electric car owners, especially since it would allow budget-conscious customers to make the most out of the company’s driver-assist and self-driving systems without committing to the features’ full price. The current price of the Full Self-Driving suite is no joke, after all, being listed at $8,000 on top of a vehicle’s cost. By offering subscriptions to features like Navigate on Autopilot with automatic lane changes, owners could gain access to advanced functions only as they are needed.
Elon Musk, for his part, has explained that ultimately, he still believes that purchasing the Full Self-Driving suite outright provides the most value to customers, as it is an investment that would pay off in the future. “I should say, it will still make sense to buy FSD as an option as in our view, buying FSD is an investment in the future. And we are confident that it is an investment that will pay off to the consumer – to the benefit of the consumer.” Musk said.
Tesla has started rolling out update 2020.36 this weekend, introducing a couple of notable new features for its vehicles. While there are only a few handful of vehicles that have reportedly received the update so far, 2020.36 makes it evident that the electric car maker has made some strides in its efforts to refine its driver-assist systems for inner-city driving.
Tesla is currently hard at work developing key features for its Full Self-Driving suite, which should allow vehicles to navigate through inner-city streets without driver input. Tesla’s FSD suite is still a work in progress, though the company has released the initial iterations of key features such Traffic Light and Stop Sign Control, which was introduced last April. Similar to the first release of Navigate on Autopilot, however, the capabilities of Traffic Light and Stop Sign Control were pretty basic during their initial rollout.

With the release of update 2020.36, Tesla has rolled out some improvements that should allow its vehicles to handle traffic lights better. What’s more, the update also includes a particularly useful feature that enables better recognition of speed limit signs, which should make Autopilot’s speed adjustments better during use. Following are the Release Notes for these two new features.
Green Traffic Light Chime
“A chime will play when the traffic light you are waiting for turns green. If you are waiting behind another car, the chime will play once the car advances unless Traffic-Aware Cruise Control or Autosteer is active. When Traffic Light and Stop Sign Control is activated, a chime will play when you can confirm to proceed through a green traffic light. To enable, tap Controls > Autopilot > Green Traffic Light Chime.
“Note: This chime is only designed as a notification. It is the driver’s responsibility to observe their environment and make decisions accordingly.”
Speed Assist Improvements
“Speed Assist now leverages your car’s cameras to detect speed limit signs to improve the accuracy of speed limit data on local roads. Detected speed limit signs will be displayed in the driving visualization and used to set the associated Speed Limit Warning.
“As usual, to adjust Speed Assist settings, tap Controls > Autopilot > Speed Limit.”

Amidst the rollout of 2020.36’s new features, speculations were abounding among Tesla community members that this update may include the first pieces of the company’s highly-anticipated Autopilot rewrite. Inasmuch as the idea is exciting, however, Tesla CEO Elon Musk has stated that this was not the case. While responding to a Tesla owner who asked if the Autopilot rewrite is in “shadow mode” in 2020.36, Musk responded “Not yet.”
Tesla has rolled out a free three-month trial subscription to Sirius XM, in what appears to be the company’s latest push into making its vehicles’ entertainment systems more feature-rich. The new Sirius XM offer will likely be appreciated by owners of the company’s vehicles, especially considering that the service is among the most popular satellite radios in the country today.
Tesla announced its new offer in an email sent on Monday. An image that accompanied the communication also teased Tesla’s updated and optimized Sirius XM UI for its vehicles. Following is the email’s text.
“Beginning now, enjoy a free, All Access three-month trial subscription to Sirius XM, plus a completely new look and improved functionality. Our latest over-the-air software update includes significant improvements to overall Sirius XM navigation, organization, and search features, including access to more than 150 satellite channels.
“To access simply tap the Sirius XM app from the ‘Music’ section of your in-car center touchscreen—or enjoy your subscription online, on your phone, or at home on connected devices. If you can’t hear SiriusXM channels in your car, select the Sirius XM ‘Subscription’ tab for instruction on how to refresh your audio.”
Tesla has actually been working on Sirius XM improvements for some time now. Back in June, for example, Tesla rolled out its 2020.24.6.4 update, and it included some optimizations to its Model S and Model X’s Sirius XM interface. As noted by noted Tesla owner and hacker @greentheonly, the source code of this update revealed that the Sirius XM optimizations were also intended to be released to other areas such as Canada.
Interestingly enough, Sirius XM is a popular feature that has been exclusive to the Model S and X. Tesla’s most popular vehicle to date, the Model 3, is yet to receive the feature. One could only hope that Sirius XM integration to the Model 3 may eventually be included in the future. Such an update would most definitely be appreciated by the EV community, especially since some Model 3 owners have resorted to using their smartphones or third-party solutions to gain access to the satellite radio service.
The fact that Tesla seems to be pushing Sirius XM rather assertively to its customers seems to suggest that the company may be poised to roll out more entertainment-based apps in the coming months. Apps such as Sirius XM, Spotify, Netflix, and YouTube, may seem quite minor when compared to key functions like Autopilot, after all, but they do help round out the ownership experience of Tesla owners. In a way, Sirius XM does make sense for Tesla’s next-generation of vehicles, especially the Cybertruck and the Semi, both of which would likely be driven in areas that lack LTE connectivity.
